Answer:
A, C, and K
Explanation:
Wireless networks use access points ( APs) for wireless communication. The APs provide a collision avoidance channel for the connected devices. Devices communicating at a channel of a given frequency would experience signal interference, so all the connected APs in a wireless network is configured to operate in different channels with considerable differences in their frequencies.
Your manager has tasked you with implementing security controls to mitigate IP spoofing attacks against your network. IP spoofing is a method of attack that involves sending packets to a target network while hiding the attacker's address using a false source address.
What method outlined would achieve anti-spoofing, to mitigate private IP spoofing attacks against your network?
Answer:
You can setup firewall rules with for example iptables on Linux. The rules should block source addresses of private IP ranges such as 192.168.*.* and 10.*. *. * etc. Check private IP ranges for full list.
It will however not guarantee prevention of IP spoofing in general as its not possible to prevent such attacks. Its the responsibility of ISPs. But the question asked for private IP spoofing and then the above works.
a) Explain 3 phase Alternative Current with aid of diagram.
Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.
A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Polyphase power systems were independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström, John Hopkinson and Nikola Tesla in the late 1880s.

The router can deliver packets directly over interfaces 0 and 1 or it can forward packets to Routers R2, R3, or R4. Describe what the router does with a packet addressed to each of the following destinations:
a. 128.96.39.10
b. 128.96.40.12
c. 128.96.40.151
d. 192.4.153.17
e. 192.4.153.90
Answer:
Following are the solution to this question:
Explanation:
In point A:
It applies the AND operation with the subnet-mask that is
[tex]=128.96.39.00001010 \ \ AND \ \ 255.255.255.10000000 \\\\= 128.96.39.0000000 \\\\= 128.96.39.0 \\\[/tex]
This corresponds to a 128.96.39.0 subnet. This is why the router sent the packet to 0.
In point B:
It applies the AND operation with the subnet-mask that is [tex]255.255.255.128[/tex]
[tex]= 128.96.40.00001100\ AND \ 255.255.255.10000000 \\\\ = 128.96.40.0000000\\\\= 128.96.40.0[/tex]
This suits the 128.96.40.0 subnet. The router then sent R2 to the packet. The packet.
In point C:
It applies the AND operation with the subnet-mask that is [tex]255.255.255.128[/tex]
[tex]=128.96.40.10010111 \ AND \ 255.255.255.10000000 \\\\= 128.96.40.1000000\\\\= 128.96.40.128[/tex]
It applies the AND operation with the subnet-mask that is [tex]255.255.255.192[/tex]
[tex]= 128.96.40.10010111 \ AND \ 255.255.255.11000000 \\\\= 128.96.40.1000000 \\\\= 128.96.40.128\\[/tex]
All of the matches of its sublinks above.
Its default R4 router was therefore sent to the router by router.
In point D:
It applies the AND operation with the subnet-mask that is [tex]255.255.255.192[/tex]
[tex]= 192.4.153.00010001 \ AND \ 255.255.255.11000000\\\\ = 192.4.153.0000000 \\\\= 192.4.153.0 \\\\[/tex]
It matches the 192.4.153.0 subnet. It router has sent packet to R3 then.
In point E:
It applies the AND operation with the subnet-mask that is [tex]255.255.255.128[/tex]
[tex]= 192.4.153.01011010\ AND \ 255.255.255.10000000 \\\\= 192.4.153.0000000 \\\\= 192.4.153.0[/tex]
There, neither of the subnet inputs correlate with the ip address with the same subnet mask.
It applies the AND operation with the subnet-mask that is [tex]255.255.255.192[/tex]
[tex]=192.4.153.01011010\ AND \ 255.255.255.11000000 \\\\ = 192.4.153.0100000 \\\\= 192.4.153.64[/tex]
It does not correlate to the subnet entries for same subnet mask, and therefore neither of the entries matches their corresponding ip address entries.
Mask of the subnet. That packet would therefore be sent to the default R4 router by the router.

Which class members should be declared as public?
a
Data attributes and constructor methods
b
Data attributes only
c
Methods and occasionally final attributes
d
Predominantly data attributes and some helper methods
Answer:
B. Methods and occasionally final attributes
Explanation:
In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.
Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.
In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.
One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.
Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.

4. When the keyword ____________________ is followed by a parenthesis, it indicates a call to the superclass constructor.
Answer:
Super
Explanation:
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.
Hence, when the keyword super is followed by a parenthesis, it indicates a call to the superclass constructor and it should be the first statement declared in the subclass constructor.

A(n) ___________ analyzes traffic patterns and compares them to known patterns of malicious behavior.a. Intrusion prevention system b. intrusion detection system c. defense-in-depth strategy d. quantitative risk assessment
Answer:b. intrusion detection system
Explanation:
An intrusion detection system (IDS) helps to alert service administrators to detect suspicious or malicious activity by monitoring and analyzing specific patterns to network traffic. Most times, the IDS may be configured to respond to suspicious malicious traffic by blocking the cyber attacker making such IP address unable to access that particular network.
An intrusion detection system (IDS) can be either a Host Based Intrusion Detection Systems (HIDS) or a Network Based Intrusion Detection Systems (NIDS) depending on preference by the user.
It is therefore necessary for businesses who require high level of security to adopt good and effective intrusion detection systems so that the communication of information from businesses to businesses can be safeguarded and secure from cyber attacks.

A scared kangaroo clears a fence that is 2.44 meters tall. What is the vertical component of the kangaroos velocity at take off ? If the horizontal component of the kangaroos velocity is 4.80 m per s at what angle did the kangaroo take off the ground? (hint: at its maximum height the kangaroos vertical velocity is 0)
Answer:
a) The vertical component of the kangaroo's velocity at take off is approximately 4.982 meters per second.
b) The angle at which the kangaroo took off the ground is approximately 46.066º.
Explanation:
a) According to the statement, the kangaroo has an initial horizontal velocity and jumps to overcome the fence until velocity becomes zero. If effects from non-conservative forces can be neglected, then we represent the situation of the kangaroo by Principle of Energy Conservation:
[tex]K_{1}+U_{g,1} = K_{2}+U_{g,2}[/tex] (Eq. 1)
Where:
[tex]K_{1}[/tex], [tex]K_{2}[/tex] - Initial and final translational kinetic energies, measured in joules.
[tex]U_{g,1}[/tex], [tex]U_{g,2}[/tex] - Initial and final gravitational potential energies, measured in joules.
By definitions of translational kinetic and potential gravitational energies, we expand and simplify the equation above:
[tex]\frac{1}{2}\cdot m\cdot [(v_{1,x}^{2}+v_{1,y}^{2})-(v_{2,x}^{2}+v_{2,y}^{2})] = m\cdot g \cdot (y_{2}-y_{1})[/tex]
[tex]\frac{1}{2}\cdot [(v_{1,x}^{2}+v_{1,y}^{2})-(v_{2,x}^{2}+v_{2,y}^{2})] = g \cdot (y_{2}-y_{1})[/tex] (Eq. 2)
Where:
[tex]m[/tex] - Mass of the kangaroo, measured in kilograms.
[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.
[tex]y_{1}[/tex], [tex]y_{2}[/tex] - Initial and final heights of the kangaroo above the ground, measured in meters.
[tex]v_{1,x}[/tex], [tex]v_{1,y}[/tex] - Vertical and horizontal initial velocities, measured in meters per second.
[tex]v_{2,x}[/tex], [tex]v_{2,y}[/tex] - Vertical and horizontal final velocities, measured in meters per second.
If we know that [tex]v_{1,x} = 4.80\,\frac{m}{s}[/tex], [tex]v_{2, x} = 0\,\frac{m}{s}[/tex], [tex]v_{2,y} = 0\,\frac{m}{s}[/tex], [tex]g = 9.807\,\frac{m}{s^{2}}[/tex] and [tex]y_{2}-y_{1} = 2.44\,m[/tex], then (Eq. 2) is reduced into this:
[tex]11.52+0.5\cdot v_{1,y}^{2}=23.929[/tex]
Lastly, we solve for [tex]v_{1,y}[/tex]:
[tex]0.5\cdot v_{1,y}^{2}=12.409[/tex]
[tex]v_{1,y}^{2} = 24.818[/tex]
[tex]v_{1,y} \approx 4.982\,\frac{m}{s}[/tex]
The vertical component of the kangaroo's velocity at take off is approximately 4.982 meters per second.
b) The angle at which the kangaroo took off the ground ([tex]\theta[/tex]), measured in sexagesimal degrees, is obtained by the following inverse trigonometric relation:
[tex]\theta =\tan^{-1}\left(\frac{v_{1,y}}{v_{1,x}} \right)[/tex] (Eq. 3)
[tex]\theta = \tan^{-1}\left(\frac{4.982\,\frac{m}{s} }{4.80\,\frac{m}{s} } \right)[/tex]
[tex]\theta \approx 46.066^{\circ}[/tex]
The angle at which the kangaroo took off the ground is approximately 46.066º.

Describe an algorithm that takes as input a list of n integers in nondecreasing order and produces the list of all values that occur more than once. (
Answer:
Input a series of integer numbers and split the string from the input to get a list. Then check and convert each string to integer with a list comprehension. Create a new variable with a value equal to the set of the list ( to get unique values) then check for the occurrence of each value in the original list.
Explanation:
This algorithm is used to check for the occurrence of values in a list that has been sorted in ascending order. This is faster if the items in the list is not converted to integer yet (still strings) before writing a for loop to check the value count in the list.
